SLB-40-250PM 40.0 mm Dia. x 250.0 mm FL; Coated; Plano-Convex Lens 400-700nm
The SLB-40-250PM is a Plano-Convex lens with a diameter of 40.0 mm and a focal length of 250.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott, a high-quality material known for its excellent optical properties.
The lens features a spherical shape, with a front surface curvature radius (R1) of 129.75 mm and a back focal length (BFL) of 247.7 mm. The edge thickness of the lens is 2 mm, while the center thickness is 3.6 mm. The effective focal length (EFL) of the lens is 250 mm, which is the distance from the lens's principal point to the focal point.
The SLB-40-250PM is coated with Opt M on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission within the 400-700nm wavelength range. The lens is currently in stock and available for immediate purchase.
